Well, in absence of TheEd's answer, I think you'll totally going to ace that 80' half marathon in the winter. However packing the autumn with 10k races is going to wear you down and so choose wisely. Most people take around 6 days to recover from a 10k race, so that will mean that you won't be able to do your key training sessions as well as you could do them, so that's gonna hamper your progress. Unless you don't 'race' every race of course. Does that make sense?
